Şeref Turhan | Aslı Kurnaz | Aybaba Hançerlioğulları
Drinking water is the most indispensable substance for humans. Bottled drinking waters are preferred over tap water with the belief that they are more nutritious, better quality, more delicious and safe in terms of health. Therefore, the Turkish bottled (spring and mineral) water market has experienced a continuous growth since 2003, as in the whole world. This study focuses on comparing the common mineral cation calcium (Ca2+), magnesium (Mg2+) and sodium (Na+) content of twenty one popular bottled spring and mineral water brands marketed in Turkey by using an inductively coupled plasma optical emission spectrometry (ICP-OES). The average concentrations of Ca, Mg and Na analyzed in bottled spring and mineral water samples were found as 14.9, 24.1 and 8.2 mg/L and 147.9, 44.3 and 117.3 mg/L, respectively. This comparison confirms that bottled natural mineral water has better quality in terms of major nutrient minerals than bottled natural spring waters.

Rabia Göçmen | Gülşah Kanbur
This study was conducted to investigate the effects of hemp seed oil replaced soybean oil as an energy supply on growth performance parameters, carcass yield, liver weight, breast meat pH, and meat color values in quails. A total of 100 one-day old quail chicks were reared in two treatment groups for 5 weeks. The experimental diets were formulated as to contain 4.4% crude soybean(control) and hemp seed oils. According to the results of the present study, crude hemp seed oil replaced soybean oil in the diet was effective on finishing body weight, feed intake, feed conversion ratio, weight gain and carcass yield. All of these parameters were lower than the soybean oil (control) group. Liver weight, and breast meat color values (L*, a*, and b*) have shown similarities between experimental groups. The breast meat pH value decreased significantly in the hemp seed oil treatment group compared to soybean oil group. Using hemp seed oil instead of soybean oil used in quail diets negatively affects performance parameters (except for feed conversion ratio).

Serkan Yeşil | Halime İrgin Ağca
Lettuce (Lactuca sativa L.) is a member of the family Compositae (Asteraceae). This plant, which is grown for its leaves, is grown in open field and greenhouse conditions almost everywhere in the world and in Turkey. With the present study virus diseases of lettuce and their prevalence in Konya province was revealed for the first time. For this purpose, leaf samples were taken from lettuce plants showing virus diseases symptoms with surveys carried out in Konya province lettuce planting areas from May to August in 2020. Then the collected lettuce leaf samples were tested in laboratory conditions by Double Antibody Sandwich Enzyme-linked Immunosorbent Assay (DAS-ELISA) method to reveal infections of Cucumber mosaic virus (CMV), Miraflori lettuce big vein virus (MiLBVV), Lettuce mosaic virus (LMV), and Tomato spotted wilt virus (TSWV). According to the information obtained from the results of the study, it was determined that 40 out of 97 (41.23%) lettuce plant samples and all (6) weed samples were infected with at least one of the viruses. In lettuce leaf samples; TSWV (27.83%), LMV (12.37%), CMV (10.31%) and MiLBVV (5.15%) infections have been detected. In weed samples; infections of CMV (83.33%), LMV (66.66%), and TSWV (50%) have been revealed. The infections of TSWV, LMV, CMV, and MiLBVV on lettuce plants in Konya province were reported firstly with the study.

2021
Rashmi Patil | Urmila Aswar
Pterostilbene (PTE) (3-5 dimethoxy-4-hydroxy-trans-stilbenes) is an analogue of resveratrol. It is extracted and isolated from a natural source of the heartwood of Pterocarpus marsupium Roxb., red grape skin, and blueberries (Vaccinium spp.). Substantial evidence suggested that PTE displayed numerous preventive and therapeutic properties in many metabolic disorders such as diabetes and obesity. Metabolic diseases result in Insulin resistance (IR) which advances to impaired sensitivity to insulin-mediated glucose disposal. The prominent role of SIRT (silent information regulator proteins) is now getting emphasized in metabolic disorders. SIRT1 represses Uncoupling protein 2 (UCP2) expressions which are further responsible for improving synthesis of ATP from glucose. This results in improving glucose utilization and insulin secretion, thus preventing IR. SIRT1 also exhibits prominent role in facilitating fatty acid mobilization thereby inhibiting adiposity. Metabolic disorders are therefore the consequences of SIRT1 downregulation. Pterostilbene, being a SIRT1 activator, increases insulin sensitivity reduces adiposity, therefore can prove to be beneficial in diabetes as well as obesity. The review summarizes therapeutic effects portrayed by Pterostilbene via the SIRT1 pathway in metabolic diseases.

Aybegün Ton
The aim of present study was to determine the effects of different ethephon doses on grain yield and yield components of two faba bean cultivars. The experiment was established in 2019/2020 and 2020/2021 cropping season at Research Area of Field Crops Department, Agriculture of Faculty, Cukurova University Adana, Turkey. The field experiment was laid out in randomized complete blocks design (RCBD) with three replications on the basis split plot design with cultivars (Luz de Otono and Histal) in main plots and ethephon doses (0, 500, 1000, 1500 g ha-1) in sub plots. Plant height (cm), branches per plant, pods per plant, seeds per plant, seed yield per plant (g), 100 grain weight (g), seed yield (kg ha-1) were investigated. Differences among the cultivars and ethephon applications were significant for seed yield and it varied from 1782 to 3388 kg ha-1 in the mean of the years. Seed yield also decreased with increasing ethephon doses. Seed yield was higher in 2019/2020 (3355 kg ha) than 2020/2021 (1841 kg ha-1) where low rainfed and high temperature. The present results suggested that ethephon applications at inititation of flowering were not useful for seed production of faba bean.

In this study, in which the effects of different applications of vermicompost on the yield and quality of San Andreas strawberry variety were investigated 15, 30, 45, 60 g vermicompost was applied per plant. First flowering, first and last harvest dates, number of fruits per plant, yield per plant (g/plant), fruit weight (g), fruit flavor, macro and micro nutrient content, organic acid amounts were examined. The results showed that the differences between treatments in yield per plant were statistically significant. The highest total yield per plant was obtained from V45 and V30 applications with 972.8 g and 878.9 g respectively and the lowest yield was obtained from the control application with 384.2 g per plant. The largest fruits were obtained from the V60 (19.5 g) application. It was determined that nitrogen, phosphorus, potassium, magnesium, sulfur, manganese, iron, zinc and boron concentrations in the leaves of strawberry plants fertilized with vermicompost were higher than the control. The highest values in organic acid values were determined in oxalic, propionic, malonic, lactic, fumaric and succinic acids in V60 application (5.62, 11.16, 49.00, 104.98 µg/100 g respectively). It seems that the application of vermicompost fertilizer in strawberry cultivation has a positive effect on yield and quality characteristics.

2021
Mehtap Çiftçi | Nilgün Öncül
Since coliform bacteria are common both in the intestine and in nature (soil, plant, etc.), they are considered as a sanitation indicator in the food industry. It is known that the majority of bacteria defined as fecal coliform in the coliform group are Escherichia coli. The presence of E. coli or fecal coliform bacteria in any sample is an indication that the necessary hygienic measures are not taken during production, storage, and sale. That means the sample is directly or indirectly contaminated with faeces, and/or other intestinal pathogens may also exist. In this study, raw milk, freshly squeezed fruit juices, unpackaged ice cream, shaved ice, and ice-cold samples were purchased from the famous touristic destination Fethiye and analyzed for coliform bacteria. For this purpose, the samples were purchased from local marketplaces, buffets, cafes, patisseries, restaurants, and roadsides at Fethiye. In total 60 samples were analyzed using Violet Red Bile (VRB) Agar. The results of coliform bacteria ranged

Macrophomina phaseolina (Tassi) Goid. is a fungal pathogen causes charcoal rot disease (Sin: Rhizoctonia bataticola) and is responsible for significant yield losses in many plants. In our study, we aimed to evaluate the antagonistic ability of 39 different bacteria, isolated from the fields of sugar beet in 2019, against the pathogen Macrophomina phaseolina isolated from sugar beet, beans and chickpeas. Approximately 31% of the bacteria showed antibiosis effect against the pathogen. It was determined that the effectiveness level of Lelliottia amnigena, Bacillus atrophaeus, B.pumilus and B. cereus (7 isolates) was moderate to high against Macrophomina phaseolina. Bacillus atrophaeus (PTo15-1a) showed the highest efficacy of 80%, 72.94% and 82.35% against Macrophomina phaseolina of chickpea, bean and sugar beet respectively. Lelliottia amnigena (Pto 14-1b) was moderately effective (57.78%) against the chickpea isolate of the pathogen. It was observed that of the seven Bacillus cereus isolates used in the experiment, three isolates (Pto14-1a, Pto12-1b, Pto17-1b) were highly effective against the chickpea pathogen, two (Pto12-1b, Pto14-2b) against bean pathogen, and one (Pto15-1b) against sugar beet isolate. Results have shown varied level of antagonism by different test bacterial against different Macrophomina phaseolina isolates, while the highest level of antibiosis shown by Bacillus atrophaeus against all pathogenic isolates indicated that it can be a potential future bioagent in managing the disease.

Tea (Camellia sinensis) is the world's most popular beverage plant, as well as an important plantation crop with high commercial value. It has been maintained for centuries through conventional vegetative propagation. Tea clonal propagation in vitro has the advantage of producing a large number of elite plants. If an efficient in vitro regeneration technology is available, this technique could be exploited for selection of tea plants for desired trait. The selected plants could be later on multiplied through in vitro or ex vitro techniques. The study aimed to induced somatic embryogenesis from immature embryo explants to genetic variaton. Different concentrations of phenylboronic acid with benzyladenine and phenylboronic acid with kinetin were tested in MS medium with 30 g/L sucrose and 8 g/L agar. MS medium without any plant growth regulators was used as control group. Considering the embryo survival rate, 1.5 mg/ L-1 phenylboronic acid + 1 mg/ L-1 kinetin produced highest result as 87.3% while lowest was in control group as 36.7%. The highest plant regeneration rate was found in 1,5 mg/ L-1 phenylboronic acid + 1 mg/ L-1 kinetin and 1.5 mg/ L-1 phenylboronic acid + 1 mg/ L-1 benzyladenine medium respectively as 58.3% and 55.6%. Kinetin treatment with increasing phenylboronic acid concentrations gave the best results in terms of somatic embryo survival rate. Also, kinetin treatment produced better results when compared to benzyladenine concentrations.
